Description

The Karbonius F8X M3 / M4 Carbon Rear Wing – Stage 1 is a purpose-designed aerodynamic component built for both track effectiveness and the refined visual character expected of a premium Karbonius product. Weighing just 3 kg, the wing is manufactured entirely from 100% prepreg carbon fiber and autoclave-cured at Karbonius' facility in Spain under ISO 9001 quality management standards — delivering motorsport-grade construction in a package that is equally at home on a race circuit or a spirited road build.

The wing is engineered for the F8X chassis specifically, developed by the Karbonius engineering team using both 2D and 3D analysis of the wing and the vehicle. The result is an aerodynamic component that generates meaningful downforce at track speeds while adding a level of visual aggression that the OEM trunk spoiler cannot match. The adjustment system is laser-engraved directly into the aluminum uprights, providing clearly marked positions for maximum downforce or maximum efficiency without guesswork.

Anodized aluminum uprights combine light weight with superior durability at the mounting interface, while the full carbon wing blade and endplates keep overall mass to a minimum. Every piece is individually numbered — a standard Karbonius practice that guarantees origin and authenticity.

  • Carbon fiber rear wing blade and endplates
